PROBLEM TO BE SOLVED: To precisely and efficiently detect the overlapped registration of the same person from a large-scaled data base where lots of personal identification items are registered. SOLUTION: The personal identification items of each person, for example, sex, data of birth, KANA name, Chinese character name, KANA address, and Chinese character address or the like are registered in individual files 7A, 7B, 7C,... of each person in a data base. A system 1 normalizes the KANA name, Chinese character name, KANA address, and Chinese character address in the individual files 7A, 7B, 7C,... into description in a unified notation method (processing 31-37). Next, the normalized identification items are compared among the files 7A, 7B, 7C,... so that whether the person is the same one, different one, or doubted one can be judged. In this judging processing, the group of the files of the same person and the doubted person is narrowed down based on the sex, data of birth, and normalized KANA name (processing 51). Then, the final judgement of whether or not the person is the same one, different one, or doubted same one is operated by using the KANA name, normalized Chinese character name, normalized KANA address, and normalized Chinese character address in each narrowed down same person group (processing 53). |
